Bottom bracket wrench for newer bottom bracket styles Crank extractor. A chain tool or chain splitter is used to 'break' a chain, in order to remove it from a bike or remove links, or to put a chain back together. A crank extractor is used to pull the crank off the bottom bracket spindle. A pedal wrench removes the pedals from the bicycle. It ...
Chainring: (one of the) front gear(s), attached to a crank; Chainset: see Crankset; Chainstay: a pair of tubes on a bicycle frame that runs from the bottom bracket to the rear fork ends; Chain tensioner: a device to maintain proper chain tension; Chaintug: a device to aid in setting the proper chain tension
Note that if a normal right-side-drive crankset is installed backwards to create a left-side-drive bicycle, the threaded pedal holes at the end of the crank arms would be reversed. In this configuration, precession may loosen the pedals over time, causing the pedals to become detached and/or damaging the pedal threading in the crank arms. A ...
Bicycle pedal, quill road type, with toe clip and toe strap (1970s) The quill pedal is a common pedal system on bicycles. It consists of a main axle section that is attached to the bicycle crank arm and contains extensions from the axle to which parallel cage plates are attached at the front and rear of the pedal.
Typical applications are in fixing a crank to its crankshaft, as in a bicycle, and a piston rod to a crosshead, as in a steam engine. The angle of the wedge determines the position of the parts being held; therefore, on a bicycle, the pedal arms will only be at 180 degrees to each other if the angle of the cotter pin's wedge is the same on both ...
The 1918 Reo owner's manual describes how to hand crank the automobile: First: Make sure the gear shifting lever is in neutral position. Second: The clutch pedal is unlatched and the clutch engaged. The brake pedal is pushed forward as far as possible setting brakes on the rear wheel.
Dynamic Runabout 7 shaft-driven bicycle Drive-shaft housing. A shaft-driven bicycle is a bicycle that uses a drive shaft instead of a chain to transmit power from the pedals to the wheel. Shaft drives were introduced in the 1880s, but were mostly supplanted by chain-driven bicycles due to the gear ranges possible with sprockets and derailleurs ...
To shift gears, the rider first moves the lever enough for the chain to jump to the next sprocket, and then adjusts the lever a slight amount to center the chain on that sprocket. An indexed shifter has a detent or ratchet mechanism which stops the gear lever, and hence the cable and the derailleur, after moving a specific distance with each ...
